MF / SOUNDGRAPH / PORTABLE GRAPH 01
One graph.
A lot of places to run it.
An open visual audio-programming platform built around a portable sound graph—not one editor, plugin format, operating system, or piece of hardware.
44 node types · 280 load-verified examples · standard-library C++ DSP core

The short version
The graph is the thing. The editor is one place it can live.
The same patch format now moves through native playback, WebAssembly in an AudioWorklet, the Godot editor, audio plugins, and embedded firmware on an ESP32-S3.
The editor can change. The hardware can change. The host can change. The portable graph remains the center of gravity.

Windows. Browser. Godot. ESP32-S3.
SoundGraph now operates as both an audio plugin and a host for third-party plugins. A modern patch has also run bit-exact on an Axoloti Core using the board’s stock firmware. The feature-freeze line remains intentionally loose while the system prepares to meet synthesizer people in person.

Why this instrument
Portable by design
Important state belongs to the graph, not the application window around it.
Readable at scale
Node anatomy, socket grammar, cables, search, previews, and source information help large patches explain themselves.
Open at the seams
The data model, DSP core, hosts, hardware adapters, and interfaces remain separable enough to inspect and change.
Mutant Factory / Chicago
New interfaces for things that already exist.
Games, instruments, tools, and the seams between them. We build the second interface, prove it works, and leave the machinery open.
